6 推荐焊接条件 Recommend Soldering Conditions
1) 焊接条件 Soldering Conditions
产品适用于回流焊 Products can be applied to reflow soldering.
① 焊接要求 Soldering conditions
预热时,产品表温与焊料温度的温差最大不允许超出 150℃,焊接完冷却时,产品表温与溶剂温度
之间的温差最大不超过 100℃。预热不足有可能引发产品表面裂纹,从而导致产品品质下降。
Pre-heating should be in such a way that the temperature difference between solder and ferrite
surface is limited to 150℃ max. Also cooling into solvent after soldering should be in such way
that the temperature difference is limited to 100℃ max. Un-enough pre-heating may cause
cracks on the ferrite, resulting in the deterioration of product quality.
产品要在以下画出的曲线允许的范围内进行焊接。其它焊接条件可能引起产品电极的腐蚀。当焊接
重复时,允许的时间为第一次做的累计时间。
Products should be soldered within the following allowable range indicated by the slanted line.
The excessive soldering conditions may cause the corrosion of the electrode. When soldering is
repeated, allowable time is the accumulated time.
